maximize their system’s potential.
GbE LAN with Bandwidth Management
GbE LAN features a network bandwidth management application which helps to improve network latency
and maintain low ping times to deliver better responsiveness in crowded LAN environments.
Smart Fan 5
With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying
cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at
different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that
support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid
cooling friendly.
5 Temperature Sensors
2 Fan Pin Headers
All Fan Pin Headers Upgraded to Hybrid Fan Headers
Interoperable Fans and Sensors
Intuitive UI for Fan Control
Intelligent Fan Control Design
Achieve fan silence. With Fan Stop, map any fan to stop completely when temperatures drop below a
specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—
all of it can be customized to your liking.
High-End Audio Capacitors
GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high
resolution and high fidelity audio to provide the most realistic sound effects for gamers.
Audio Noise Guard
GIGABYTE motherboards feature an audio noise guard that essentially separates the board’s sensitive
analog audio components from potential noise pollution at the PCB level.
